<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I'm not sure we should provide a jitter buffer at the channel driver level. Since people have the option of placing jitter buffers on the read side of the channel using JITTERBUFFER, giving them the option through the channel driver seems to provide them a less flexible, and less preferred, mechanism of doing something they already can do.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">The session should not have a pointer back to the endpoint, as it implies a strong association from the session to the endpoint that doesn't exist. The danger here is that a circular dependency makes the locking order and the ownership semantics difficult to enforce.
As this is only used during a hangup to notify the endpoint that one of its session objects has gone away, why not just cache the endpoint name? Then you can safely do a lookup and ask the endpoint to remove the session. This creates a much weaker reference between the session and the endpoint, and if the endpoint goes away during a hangup (such as during a CLI reload), there's less room for error.</pre>

In general, I'd expect the channel to always be locked first, followed by the session object. If the session object is locked and need to access the channel - either by bumping its ref count or by actually obtaining a lock - there should be a consistent mechanism that does this that preserves the locking order and does not rely on deadlock prevention or result in double locks (just because we use recursive mutexes doesn't mean we should rely on them when we don't have to). More on this later.</pre>

If this is to replace the current chan_jingle, then I'd propose we name it Jingle, and the current chan_jingle would be renamed to chan_jingle_deprecated, or something like that. The old channel driver could be named something to indicate its deprecated status and kept in case there is some element of backwards compatibility we missed, but I'd prefer people to just use the improved channel driver.

You *should* be able to use a string with characters, but some of the ones I found during my testing require this to be numerical - so I just hash what our ICE implementation gives us (which right now contains characters, naturally).</pre>

RTCP support is setup on RTP always because we don't know if it will or will not be used, as a result this generates RTCP candidates. By adding a log statement in here every time this code is hit messages will be output about RTCP candidates.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I don't think we should be using ast_channel_trylock on the session owner. This appears to be a workaround to the locking order difficulties that exist between a channel and it's pvt.
In general, this should probably follow the same mechanism as sip_pvt_lock_full. This would use something like the following:
while (attempt_again)
lock session
set candidate_channel = session->owner
if candidate_channel
ref candidate_channel
else
unlock session and return
unlock session
lock candidate_channel
lock session
if (candidate_channel != session_owner)
unlock everything and retry
else
do not attempt again
At the end of this, the channel reference has been bumped one, and the channel and the session have been locked in the correct order.
In some cases in chan_jingle2, we only need to ensure that the channel object does not get removed while we're performing some operation. In those cases, a different method could be written similar to this that stops once the channel ref count has been bumped.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Per my earlier comment this is now using the lock_full strategy that is present in chan_sip, but just like that... the locks are still locked. This is because while you can ensure the channel does not go away you can't ensure that you are performing actions on the *correct* channel without locking it so masquerading does not occur.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This method shows why the locking order needs to be channel then session. In this method, while the channel is locked, we at the very least partially destroy the session. We do this in situations where the session would be locked (implying it shouldn't change), but the channel has not yet been locked.
In the current code, the order is often reversed and the session is locked and we do what amounts to deadlock prevention to gain a lock on the channel. In that situation, the session could be locked while this method is executed. In this method we would have the channel lock and, at the very least, partially destroy the session object. When we unlock the channel, the session object has been removed from the endpoint and the channel, but the thread that was in the deadlock prevention believes that it has obtained a valid channel associated with the session.

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I have now fixed this. The session is locked during this procedure and once unlocked anything blocking should gracefully handle the situation.</pre>

It means something happened internally within the "switch" or in our case application that caused it to fail.</pre>

It would seem that if a session does not have an owner, there's no need to attempt to get the owner lock.
I'll grant that the current implementation of jingle_get_owner_lock handles this, but on a first pass through the code it makes the lock/unlock pair appear unbalanced.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">There are race conditions in this code. During a reload, if an endpoint is marked for deletion, nothing stops a new jingle channel being created for that endpoint.
Ideally, during a reload there'd be a single point in time in which the endpoints are swapped out. Channels that were created for a newly deleted endpoint would keep the old endpoint alive until the channel went away, at which point the endpoint object would be destroyed.
Terry's new config work should make this type of operation possible without needing a destroy flag.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Fixed the race condition. Ultimately yes this will be migrated to Terry's code and heck it may take long enough to get ICE/STUN/TURN in and then this to be able to do it before it is merged in. We'll see.</pre>

It has been written to the specs available and tested extensively.
ICE and STUN support for Jingle uses the new ICE/STUN/TURN support which is present in another review. (Please do not review any of that code in this review)
STUN support for Google uses the existing STUN implementation, as the new support is not compatible with it.</pre>
